2011-02-25Send warning instead of abort on EBUSY from pthread_mutex_destroyRickard Green
Due to a bug in glibc the runtime system could abort while trying to destroy a mutex. The runtime system will now issue a warning instead of aborting.

2011-02-23beam_emu: Eliminate redundant #ifdefBjörn Gustavsson
The halfword emulator used to require special handling, but no longer does.
2011-02-23beam_emu: Remove unnecessary decrement of I in "case_end r"Björn Gustavsson
It is not necessary to decrement I, because an exception is about to be generated. Furthermore, I pointing *before* the instruction that caused the exception may cause problems in the future.

2011-02-03HALFWORD ETS relative termsSverker Eriksson
In halfword emulator, make ETS use a variant of the internal term format that uses relative offsets instead of absolute pointers. This will allow storage in high memory (>4G). Preprocessor macros (like list_val_rel(TERM,BASE)) are used to make normal (fullword) emulator almost completely unchanged while still reusing most of the code.
2011-01-18Lower the maximum arity from 256 to 255Björn Gustavsson
Historically, for no good reason, a function is allowed to have from 0 to 256 arguments. Thus, the number of arguments *almost* fits into a byte. HiPE only supports up to 255 arguments (because it assumes that the function arity fits into a single byte), and fixing that limitation would require ugly special-case handling. In Dialyzer, the arity type is defined to be a byte (i.e. 0..255). Since no-one uses functions with 256 arguments anyway, lower the limit to 255.

* bjorn/beam-loader/OTP-9030: (43 commits) c: Reduce memory footprint erl_posix_msg: Reduce memory footprint Introduce a few more variations of the move instructions Combine a move + jump sequence into the move_jump instruction Optimize and clean-up the exact equality/non-equality instructions Optimize addition of a small integer to a variable Introduce a special instruction for select_val with two values Introduce a few more specialized put_list instructions Eliminate the "put_list c n Dst" instructions Eliminate the specific move_sd instruction Eliminate use of GetArg1() in the badmatch and case_end instructions Eliminate use of GetArg2() in the i_element instruction Eliminate use of GetArg1() in the fast_element instruction Eliminate use of GetArg1() in the jump_on_val* instructions Eliminate use of GetArg1() in the select_val instruction beam_emu: Eliminate sloppy use of tmp_arg1 and tmp_arg2 beam_emu: Don't inline helper functions into process_main() beam_emu: Clean up calling of the error_handler module Simplify a select_val instruction that selects only one value Optimize creation of tuples ...
2011-01-17Introduce a few more variations of the move instructionsBjörn Gustavsson
Frequency counts show that move Const x(1) move Const x(2) are very common.
2011-01-17Combine a move + jump sequence into the move_jump instructionBjörn Gustavsson
That will save one word and small amount of time for each occurrence.
2011-01-17Optimize and clean-up the exact equality/non-equality instructionsBjörn Gustavsson
The is_eq_exact/3 and is_ne_exact/3 instructions are commonly used with one immediate or literal operand. Introduce three new specialized instructions: i_is_eq_exact_literal/3 i_is_ne_exact_immed/3 i_is_ne_exact_literal/3 The i_is_ne_exact_literal/3 instruction is not very frequently used, but its existence is justified because we removed in a a previous commit the special instruction for matching bignums and we now use i_is_ne_exact_literal/3 instead. For consistency, rename the existing is_eq_immed/3 instruction to is_eq_exact_immed/3. While at it, remove the optimization of an is_eq/3 instruction with an immediate operand because that optimization is already done by the compiler.
2011-01-17Optimize addition of a small integer to a variableBjörn Gustavsson
Introduce a new i_increment/4 to optimize the addition of a register and a small integer. This instruction saves two instruction words compared to the standard instructions (an i_fetch/2 instruction followed by a i_plus/3 instruction) and will also be slightly faster.
2011-01-17Introduce a special instruction for select_val with two valuesBjörn Gustavsson
The new instruction will save one word (because no size operand is needed), and is slightly faster. Handle select_tuple_arity in the same way.
2011-01-17Introduce a few more specialized put_list instructionsBjörn Gustavsson
2011-01-17Eliminate the "put_list c n Dst" instructionsBjörn Gustavsson
Since the literal (constant) pool was introduced in R12, the BEAM compiler will never generate a "put_list Const [] Dst" instruction (it will instead generate a "move [Const] Dst" instruction).
2011-01-17Eliminate the specific move_sd instructionBjörn Gustavsson
The move_sd specific instruction is no longer used since there are specific move instructions covering all possible permutations of operands. Also eliminate the move_cy instruction because it is almost never generated by the compiler.
2011-01-17Eliminate use of GetArg1() in the badmatch and case_end instructionsBjörn Gustavsson
Create separate instructions for each register type. The "badmatch x(0)" and "case_end x(0)" (which are very common) will only require a single word each, compared to two words when GetArg1() is used.
2011-01-17Eliminate use of GetArg2() in the i_element instructionBjörn Gustavsson
Use separate instructions for each register type.
2011-01-17Eliminate use of GetArg1() in the fast_element instructionBjörn Gustavsson
Use separate instructions for each register type.
